Application May 5, 1944, Serial No. 534,379

- 2 Claims.

My invention relates to a swivel flush set, and an important object of the invention is to provide such a device that is comprised of fewer parts and is easier to assemble.

Still another object of the invention is to provide a swivel fiush set that permits a relatively wide latitude of swivel action.

A further object is to provide this type of fiush set that may be used in places that are particularly difficult to reach with other tools.

My invention also has for its objects to provide such means that are positive in operation, convenient in use, easily installed in working position and easily disconnected therefrom, economical of manufacture, relatively simple, and of general superiority and serviceability.

.The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in the course of the following description. However, the drawings merely show and the following description merely describes one embodiment of the present invention, which is given by way of illustration or example only.

In the drawings, like reference characters designate similar parts in the several views.

Fig. 1 is a longitudinal section, partly in elevation, of a swivel type flush set embodying the foregoing specifications.

Fig. 2 is an end elevation looking in the direction of the arrows 22 of Fig. 1.

Referring more in detail to the drawings, the reference number 3 generally indicates a shank that is ribbed at 1 and carries a ball 5. A rivet set member 6 has a socket l at its inner end and arranged to be engaged by the ball 5. The outer face of the rivet set member 6 is dished as suggested at IT. A rim 8 is disposed on the member around the concavity ii in the end face of the rivet set 6.

A resilient rubber sleeve 9 has an inward flange iii behind the ball 5 and the sleeve also grips a circumferential groove i2 around the rivet set member 6, thereby holding the members of the ball and socket connection together. A lip l3 extending from the end of the sleeve 9 provides a suction grip with the part being riveted, and in addition, avoids scratching of the part.

A coil spring i4 is arranged around the shank 3. The outer end I5 of the spring is of reduced diameter and hooks around the rib 4 and is arranged 2 between rib 4 and the opposed end of the sleeve 9.

In use, the shank 3 is yieldingly held in a riveting gun (not shown) by the spring l4, since the end It of the spring is fastened to the gun in any suitable manner. In practice, the spring i4 absorbs shocks of the riveting and acts as a return spring for the set, during operation. The lip I3 is placed around the end of the rivet (not shown), while the set 8 upsets the end of the rivet. The recess i1 tends to center the set on the rivet end.

The rubber sleeve 9 has several functions. It serves as a protection against scratching the part being riveted; it holds the set and shank members in their operative relationship; and it provides a suction grip with the part being riveted, around the rivet.

While I have illustrated and described what I now regard as the preferred embodiment of my invention, the construction is, of course, subject to modifications without departing from the spirit and scope of my invention. I, therefore, do not wish to restrict myself to the particular form of construction illustrated and described, but desire to avail myself of all modifications that may fall Within the scope of the appended claims.

Having thus described my invention, What I claim and desire to secure by Letters Patent is:

1. A swivel type rivet set including a shank having a ball at an end thereof and of greater diameter than said shank, a set member having an upsetting face at one end and at the other end formed with a semispherical pocket for mutual cooperation with said ball to provide for flexible movement therebetween, said set member having between the ends thereof a circular groove, and a rubber sleeve flexibly connecting said ball and set member, said sleeve having a cylindrical opening to fit about said shank and an annular curved face to fit over the upper half of said ball, and the interior of said sleeve formed with an inwardly directed head for seating in the groove of said set member.

2. A rivet set including a shank having a shoulder and a ball integral with the end of said shank and spaced from said shoulder to form a recess between said ball and shoulder, a set member having a semispherical cavity at one end to accommodate a portion of said ball, and an enlarged anvil at the other end, said set member having an annular groove between said anvil REFERENCES CITED The following references are of record in the file of this patent:
